4.3.2. Filter insertion loss test for POTS port :

CPF104IG

The insertion loss of a device connected into a given transmission system is defined as the

ratio, expressed in dB, of the load power available(before and after insertion ) delivered to

the output network beyond the point of insertion at a given frequency. In general , the

insertion loss of a device inserted in a given transmission system mainly caused by internal

component resistive loss while all of the impedance between source , load and device

interface having been matched. To perform the insertion loss measurement ,thru calibration

must be done prior the testing . General Insertion loss equation can be expressed as

following.

Insertion loss = 20 log V2 / V1 dB where

V1 = the measured voltage value of load without LPF in circuit.

V2 = the measured voltage value of load with LPF in circuit.

The test setup is shown in drawing below. :
